A 16 sided polygon
If the interior angles add up to 1800 degrees then it is a 12 sided polygon.
A regular polygon having an interior angle measure of 168o has 30 sides and is called a triacontagon.
180 - interior angle = exterior angle
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
Each interior angle will measure 156 degrees
Each interior angle will measure 162 degrees
If the measure of an interior angle of a regular polygon is 140o, the polygon is a nonagon (sometimes called an ennagon) having 9 sides.
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing that it is a regular polygon then each interior angle will measure 160 degrees
Im stuck on that too :/
In geometry, an interior angle is an angle formed by two sides of a simple polygon that share an endpoint, namely, the angle of the inner side of the polygon.
